How do I join the social media profile details with my customer personal details?

Industry:- Retail

Requirement:-

I need to verify and validate the social media profile detail with my customer detail within KNA1 table. Tables SOCIALDATA and SOCIALUSERINFO will hold the customer's social media profile details. Also, I will have my existing customer details within KNA1. I want to join customer's personal details with their social media account details. How do I go about it?

Any help would really be appreciated.

Thanks!
